Google has done it again... now with their beta Ride Finder Service. Its currently only supported in about 10 cities (Milwaukee being one of them). You can use it to see the real time location of taxis in your city.

Now here's a scary thought. With more companies fitting GPS location in new automobiles... when will Google be able to show you the location of your car in real time? Tell your wife you had to work late? Soon she'll be able to go to Google LoJack and see that you're actually at a bar. Mark my words... the day is coming.
